Hi rtpengine team,

I'm encountering an issue where the EVS codec is not supported after compiling rtpengine, despite obtaining the necessary 3GPP EVS files(R18).
Steps to Reproduce:

1. Downloaded the 3GPP EVS codec reference implementation from the 3GPP website (TS 26.442).
2. Cloned the rtpengine repository:
3. fllow those step
   “To supply the codec implementation as a shared object during runtime, extract the reference implementation’s .zip file and apply the provided patch (from here) that is appropriate for the chosen implementation. Run the build using make (suggested build flags are RELEASE=1 make) and it should produce a file lib3gpp-evs.so. Point rtpengine to this file using the evs-lib-path= option to enable support for EVS.”
